Several agitators for generating a mixture are described which generally have a housing and an impeller rotatably mounted within the housing. The impeller has a first end with a first end face, and plurality of protuberances and at least one compressed gas channel outlet disposed on the first end face. The agitator also has a mixing chamber that is located adjacent to the plurality of protuberances, a fluid inlet extending through the housing for supplying a mixing fluid to the mixing chamber, and a fluid outlet extending through the housing for discharging the mixture from mixing chamber. When the compressed gas and the mixing fluid are supplied to the mixing chamber, the compressed gas becomes uncompressed gas, and rotation of the impeller agitates the uncompressed gas and the mixing fluid and disperses the uncompressed gas and at least a portion of the mixing fluid to generate the mixture.

An agitator is capable of more efficiently applying a shear force to a treatment target fluid through the action of an intermittent jet flow. The agitator includes a rotor which includes blade, and a screen concentric therewith, the rotation of at least the rotor causing a treatment target fluid to pass through slits in the screen to become an intermittent get stream, which is discharged from inside the screen to the outside thereof, wherein the agitator is characterized in that: the screen has a cylindrical shape with a circular cross section; openings of the slits provided in an inner surface of the screen constitute flow intake openings; openings of the slits provided in an outer surface of the screen constitute flow discharge openings; spaces between the flow intake openings and the flow discharge openings constitute slit space; and the circumferential-directional width (So) of the flow discharge openings and the circumferential-directional width (Si) of the flow intake openings are greater than the circumferential-directional width (Sm) of the slit spaces.

Devices for treating aqueous pulps of organic materials usable in the food industry, perfumes, in the production of technical and food alcohol, in the processing of organic waste, etc., are provided. A rotary-pulsation device contains a drive, a stator, and a rotor installed in a housing. A vibration sensor is installed on an outer side of the stator to diagnose conditions of the working bodies and for continuous correction the shaft rotation speed. Reliability of the rotary-pulsation device and processing efficiency are increased by reducing manual cleaning related stops and breakage-related failures. The scope of usage is expanded because automatic processing of water pulps containing large-sized and extended fragments becomes possible; the treated pulp is saturated with small gas bubbles; and automation capabilities may be expanded when integrating the device into substrate processing systems.

A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.

An apparatus for mixing a liquid or pasty product. The apparatus comprises a first housing part (11) and a second housing part (12) assembled together. The assembly of the first housing part (11) and the second housing (12) part forms•—a housing inner space (17) between an inlet (4) and an outlet (5), •—a cooling jacket (7) for circulation of a coolant fluid around the housing inner space (17), and•—a buffer jacket (9) for circulation of a clean fluid, the buffer jacket (9) being formed between the cooling jacket (7) and the housing inner space (17). The buffer jacket protects the mixed product from contamination by the coolant fluid. It also facilitates detection of leakage between the housing inner space and the buffer jacket. The invention also relates to a corresponding method.

Reactors, reactor systems and methods for producing particles in a precipitation process are provided. The reactor includes a housing defining a reaction chamber, a stator assembly including two or more stators, a rotor assembly including two or more rotors, the rotor assembly configured for rotation about an axis of rotation relative to the stator assembly, a first inlet to supply a first reactant material to the reaction chamber at a first radial location, a second inlet to supply a second reactant material to the reaction chamber at a second radial location different from the first radial location, wherein the first and second reactant materials react to produce precipitation of particles in the reaction chamber, and an outlet to supply the particles formed in the reaction chamber.

In the case of a rotor (109) for a device for mixing powder and liquid, a number of connecting arms (203) are formed, as a connecting structure, between an outer blade carrier plate (215), which is equipped with outer blades (127), and a shaft receptacle (117), between which connecting arms there are situated liquid outlet regions (206). This has the result, owing to a relatively high throughput with a shear action which is still sufficient, of a relatively high mixing rate and of a relatively low tendency for powder to agglutinate.

Provided are an immediately-before-stirring-type fluid processing device and an immediately-before-stirring-type fluid processing method that can adjust or improve the final properties of a fluid to be processed that is introduced as a raw material into an annular flow channel of a microreactor employing the annular flow channel, which is formed between relatively rotating processing surfaces, as a flow channel in which fluid processing is performed. A fluid to be processed, which has been prepared in a fluid preparing system so as to be in an ideal state for reaction, is charged into a fluid processing device. The fluid processing device subjects the fluid to be processed to reaction processing in an annular flow channel, which is formed between two processing surfaces. A cylindrical stirring space is provided in the radially inner side of the annular flow channel, and a rotor and a screen are disposed inside the stirring space. Stirring energy is applied by the rotor and a shearing force is applied between the rotor and the screen to the fluid to be processed immediately before the fluid to be processed is introduced into the annular flow channel.

A mixing system mixes liquid adhesive and gas to create a solution. The mixing system it a manifold defining an adhesive input that receives the liquid adhesive, a gas input that receives the gas, a mixing chamber in fluid communication with the adhesive and gas inputs, an output that outputs the solution, and an output passage extending from the mixing chamber to the output. The mixing system also includes a rotor that rotates within the mixing chamber about a longitudinal axis so as to mix the solution, a motor that rotates the rotor, and a static mixer positioned within the output passage that statically mixes the solution flowing through the output passage.
